Fermilab experiment discovers a heavy relative of the neutron

(PhysOrg.com) -- Scientists of the CDF collaboration at the Department of Energy's Fermi National Accelerator Laboratory announced the observation of a new particle, the neutral Xi-sub-b (Ξb0). This particle contains three quarks: a strange quark, an up quark and a bottom quark (s-u-b). While its existence was predicted by the Standard Model, the observation of the neutral Xi-sub-b is significant because it strengthens our understanding of how quarks form matter

Humanity’s Biggest Impact May Be The Exctinction Of Predators

The death of large predators isn't just a tragedy, it can lead to the utter destruction of whole ecosystems--something that is already happening in many parts of the world. You may not have noticed, but we are in the early to middle stages of the Earth's sixth large extinction event. Compared to the

Scientists drag light by slowing it to speed of sound

(PhysOrg.com) -- Scientists at the University of Glasgow have, for the first time, been able to drag light by slowing it down to the speed of sound and sending it through a rotating crystal.

iFive: Pandora Prices IPO, China-U.S. Cyber War?, Color Loses Founder, Next-Gen Xbox In Testing, Garmin Buys Navigon

This is the complete rear face of the sun, imaged for the first time in this manner by NASA's two STEREO solar imaging spacecraft on June 1. It's intriguing, and also relevant: Scientists are predicting that the next 11-year Solar Cycle could be very muted, which some suggest leads to an extended period of cold weather on Earth.

Can A Black Stain Lead The Hydrogen Economy?

Just in case the whole electric-car revolution doesn't pan out, vehicle manufactures have been hedging their bets with hydrogen-powered vehicles; just last week, Toyota opened the first hydrogen refueling station connected directly to a hydrogen pipeline. But human production of hydrogen from water is often a dirty process--most hydrogen today is produced from natural gas. Plants, however, split water all the time

Mapping deformation in buried semiconductor structures using the hard X-Ray nanoprobe

(PhysOrg.com) -- Scientists from IBM's T. J. Watson Research Center and Columbia University, working with the X-Ray Microscopy Group, have mapped rotation and strain fields across a silicon-on-insulator (SOI) structure that included a liner of stressed Si3N4 using X-ray nanodiffraction (nano-XRD) at the CNM/APS Hard X-Ray Nanoprobe beamline.
